IK Constraint Wackiness

Hi,
In my quick attempt to fix the flipping problem.

  1. I made the Trunion itself into a Hinge (X).

  2. I also added some extra lines (Aimer + Connector) to control the rotation of the JackShaftCamFollowers. One JackShaftCamFollower was made the “child” of the other so as to make the other one do the same trick.

  3. I also added an extra point (PT_TRUNION_FLIPPER) as a Child to the Trunion, located at the same location as the the ActuatorRamFocusPoint (which iis constrained to the JackshaftFocusPoint which follows the JackshaftPath), and made this new point constrained to the JackshaftFocusPoint as well.

With the extra step inbetween - adding an explicit hinge at §1 above - the Trunion cannot flip like crazy anymore.

I didn’t check the reasons for the broken constraints, they probably stem from some slight imperfections in locating the focal points (detach, relocate, and put the IK-chain together again).
